[0030] The application will be described in further detail below with reference to the drawings. Like elements in different embodiments are denoted by like reference numerals. In the following description, numerous specific details are described to provide a thorough understanding of the application. However, those of skill in the art will recognize that the application can be practiced without one or more of the specific details. In other instances, well-known structures have not been described in order to avoid obscuring the application. Furthermore, the skilled artisan will recognize that some of the features described herein can be implemented in a different manner than that described.

[0031] In addition, the features, operations, or functions described in the specification can be combined in any suitable manner in various embodiments. In addition, the various steps or acts in a method may¬be rearranged, combined, or divided in any suitable manner. Accordingly, various sequences or order of acts or steps described in the specification are not intended to be limiting, unless otherwise specified. The specification and drawings are, therefore, to be regarded as illustrative rather than restrictive.

[0032] The serial numbers of components in the specification, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any sequence or technical meaning. The application also includes "connection" and "coupling", unless otherwise specified.

[0033] The vacuum negative pressure system disclosed in the application is mainly applied in the field of medical devices, and is used for massage and auxiliary treatment of a target part of a human body. For example, the system can be used for massage of male genital organs to assist in the treatment of male sexual dysfunction and erectile dysfunction.

[0034] The vacuum negative pressure system disclosed in the application comprises a vacuum chamber 3 and negative pressure pumps, the vacuum chamber 3 is used for sealing contact with a target part of a human body; the negative pressure pumps are provided with two, which are a first negative pressure pump 1 and a second negative pressure pump 2, a first suction end 11 of the first negative pressure pump 1 is communicated with the vacuum chamber 3, and a first exhaust end 12 of the first negative pressure pump 1 is communicated with an external environment; a second suction end 21 and a second exhaust end 22 of the second negative pressure pump 2 are both communicated with the vacuum chamber 3; the first negative pressure pump 1 and the second negative pressure pump 2 can work cooperatively to generate an air pressure wave in the vacuum chamber 3, so as to realize massage and auxiliary treatment on the target part of the human body.

[0035] Specifically, please refer to Figures 1 to 4 The vacuum chamber 3 has an opening and a containing cavity, the containing cavity is used for containing a target part of a human body, such as a male genital organ, and the opening is used for sealing cooperation with the human body, and an interface for realizing communication with the negative pressure pump is arranged on a chamber wall of the vacuum chamber 3.

[0036] Generally, the negative pressure pump has a reciprocating or rotating moving part, such as a plunger pump, an electromagnetic pump or a vane pump, and the moving part moves for one cycle to form one pump gas cycle of the negative pressure pump; the pump gas flow of the negative pressure pump is different at different time periods in one pump gas cycle, for example, one pump gas cycle of the negative pressure pump comprises a first time period and a second time period, the first time period can be considered as a time period in which the moving part moves towards a first direction, and the second time period can be considered as a time period in which the moving part moves away from the first direction, the first direction can be a certain linear direction or a circumferential direction around a certain center; the pump gas flow of the negative pressure pump is the largest in the first time period and the smallest in the second time period.

[0037] In the initial stage of the negative pressure pump pumping the vacuum chamber 3, the pump gas flow is different at different time periods in one pump gas cycle, when the pump gas flow decreases in one pump gas cycle, the gas downstream of the pump gas pipeline will hinder the gas upstream of the pump gas pipeline, due to the inertial effect, the pressure of the hindered gas is uneven, and an air pressure wave is generated in the vacuum chamber 3.

[0038] If only one negative pressure pump is arranged in the vacuum negative pressure system, when the negative pressure pump pumps the vacuum chamber 3, due to the gradual decrease of the gas molecules in the vacuum chamber 3 and the gradual decrease of the air pressure, when the movement power of the moving part in the negative pressure pump is equal to the resistance of the negative pressure to the moving part, the negative pressure pump will reach a balance state, and the movement amplitude of the moving part will gradually decrease due to the action of the negative pressure in the system, which means that the pump gas flow of each pump gas cycle gradually decreases, and the air pressure wave generated in the vacuum chamber 3 also decreases.

[0039] In this application, two negative pressure pumps are provided. The first negative pressure pump 1 is connected to the vacuum chamber 3 only at its first suction end 11, and is used to draw air from the vacuum chamber 3. The second negative pressure pump 2 is connected to the vacuum chamber 3 at both its second suction end 21 and its second exhaust end 22, and is used to achieve airflow circulation within the vacuum chamber 3. Since the pressure at the second suction end 21 and the second exhaust end 22 of the second negative pressure pump 2 is the same, the force of the air pressure on the moving parts in the second negative pressure pump 2 can be ignored. Thus, the pressure in the vacuum chamber 3 will not affect the movement amplitude of the moving parts in the second negative pressure pump 2, that is, the second negative pressure pump 2 will continuously generate air pressure waves in the vacuum chamber 3. Furthermore, the pumping cycles of the two negative pressure pumps are the same. During the same period, both negative pressure pumps operate at maximum pumping flow rate, and during the same period, both operate at minimum pumping flow rate. In this way, the two negative pressure pumps work together, and the air pressure waves generated by the two negative pressure pumps in the vacuum chamber 3 can be superimposed, thereby increasing the size of the air pressure waves in the vacuum chamber 3. A larger air pressure wave applied to the target area of ​​the body will create a vibration massage, reducing pain during use, increasing blood circulation in the target area, and helping to improve the user's experience and effectiveness.

[0040] Specifically, in some embodiments, please refer to Figure 2 The vacuum negative pressure system also includes a main control board 4, and the first negative pressure pump 1 and the second negative pressure pump 2 are both electrically connected to the main control board 4. The vacuum negative pressure system has a first mode. In the first mode, the main control board 4 controls the first negative pressure pump 1 and the second negative pressure pump 2 to turn on. The first negative pressure pump 1 is used to draw air from the vacuum chamber 3, and the second negative pressure pump 2 is used to circulate the air in the vacuum chamber 3 (the direction indicated by the dashed arrow in the figure is the gas flow direction). The pumping cycles of the first negative pressure pump 1 and the second negative pressure pump 2 are the same. In this way, the main control board 4 controls the entire vacuum negative pressure system to work in the first mode, so as to facilitate the control of the entire vacuum negative pressure system.

[0041] Of course, to save costs, the main control board 4 can be omitted, and the user can manually control the operation of the first negative pressure pump 1 and the second negative pressure pump 2 respectively.

[0042] Furthermore, in some embodiments, please continue to refer to Figure 2, the vacuum negative pressure system further comprises a buffer gas tank 5, which is connected in series between the second exhaust end 22 of the second negative pressure pump 2 and the vacuum chamber 3. The buffer gas tank 5 can increase the gas capacity in the vacuum negative pressure system, so that the gas in the buffer gas tank 5 can be supplemented into the vacuum chamber 3 in the first mode, so that the gas pressure wave acting on the target part of the human body becomes softer and more elastic, which helps to increase the comfort of the user during use and reduce pain and discomfort. Of course, in the case that the length of the air pipe between the second negative pressure pump 2 and the vacuum chamber 3 is long and the inner diameter of the channel is large, the air pipe can accommodate more gas to increase the gas capacity of the vacuum negative pressure system, so that the buffer gas tank 5 does not need to be separately arranged in the vacuum negative pressure system.

[0043] In some embodiments, the vacuum negative pressure system further comprises a gas pressure sensor 6, which is electrically connected to the main control board 4, and the gas pressure sensor 6 is used to detect the gas pressure in the vacuum chamber 3. The gas pressure sensor 6 can be arranged in the vacuum chamber 3 and mounted on the wall of the vacuum chamber 3. The connecting wire on the gas pressure sensor 6 is electrically connected to the main control board 4 through the interface arranged on the wall of the vacuum chamber 3, and the gas pressure sensor 6 transmits the detected gas pressure signal to the main control board 4.

[0044] Of course, in other embodiments, please refer to Figures 1 to 4 The gas pressure sensor 6 can also be mounted on the main control board 4 and electrically connected to the main control board 4. The vacuum negative pressure system further comprises a first three-way joint 7, and the three interfaces of the first three-way joint 7 are respectively communicated with the gas pressure sensor 6, the buffer gas tank 5 and the vacuum chamber 3 through the air pipe. In this way, since the buffer gas tank 5 is communicated with the gas pressure sensor 6, the gas flow fluctuation entering the gas pressure sensor 6 can be reduced, which helps to improve the detection accuracy and precision of the gas pressure sensor 6 on the gas pressure in the vacuum chamber 3.

[0045] Further, the vacuum negative pressure system can also be provided with a display screen, which is electrically connected to the main control board 4. The main control board 4 can convert the received gas pressure signal in the vacuum chamber 3 into a digital signal and display it on the display screen, so that the user can know the gas pressure information in the vacuum chamber 3. Of course, the display screen can also be a touch screen, and the user can input mode parameters or pressure parameters through the display screen to control the switch and power of the negative pressure pump through the main control board 4.

[0046] In some embodiments, please refer to Figure 3, the vacuum negative pressure system further comprises a first valve 8 and a second valve 9, the first valve 8 and the second valve 9 can be solenoid valves and are electrically connected with the main control board 4, of course, the first valve 8 and the second valve 9 can also be other switch valves which can be controlled by the main control board 4 to realize switching. The first valve 8 is connected between the second exhaust end 22 of the second negative pressure pump 2 and the buffer gas tank 5, and the second exhaust end 22 of the second negative pressure pump 2 is also connected with the external environment through the second valve 9; the vacuum negative pressure system further has a second mode, in the second mode, the main control board 4 controls the first valve 8 to be closed, the second valve 9 to be opened, and the first negative pressure pump 1 and the second negative pressure pump 2 to be opened, the pumping period of the first negative pressure pump 1 is the same as that of the second negative pressure pump 2, and the first negative pressure pump 1 and the second negative pressure pump 2 are used to suck the air in the vacuum chamber 3 (the direction of the arrow with a dashed line in the figure is the direction of the gas flow), and the buffer is used to supply air to the vacuum chamber 3.

[0047] Specifically, the first valve 8 is located between the second exhaust end 22 of the second negative pressure pump 2 and the buffer gas tank 5, so as not to affect the air supply of the buffer gas tank 5 to the vacuum chamber 3, and also not to affect the detection accuracy of the air pressure sensor 6. Of course, in other embodiments, if the detection accuracy of the air pressure sensor 6 is not high, the first valve 8 can also be arranged between the buffer gas tank 5 and the vacuum chamber 3. The second exhaust end 22 of the second negative pressure pump 2 is connected with the external environment through the second valve 9, and the whole vacuum negative pressure system can be provided with only one exhaust port 102 connected with the external environment, and the exhaust port 102 can be connected with the first exhaust end 12 of the first negative pressure pump 1 and the second valve 9 through a three-way joint, which is helpful to simplify the structure of the whole vacuum negative pressure system.

[0048] In the second mode, the main control board 4 can control the first valve 8 to be closed, the second valve 9 to be opened, and the first negative pressure pump 1 and the second negative pressure pump 2 to be opened, please refer to Figure 3 , so that the two negative pressure pumps are used to suck the air in the vacuum chamber 3, and the buffer gas tank 5 is used to supply air to the vacuum chamber 3, and since the pumping periods of the two negative pressure pumps are the same, under the synergistic action of the two negative pressure pumps, the vacuum negative pressure system can realize the functions of rapid air suction and air release of the vacuum chamber 3, so that the human target part can experience the effect of rapid stretching and relaxation, and the function diversification of the vacuum negative pressure system is realized, and if the target part is the male genital organ, the vacuum negative pressure system can realize the massage function of the male genital organ, which is helpful to increase the blood circulation of the male genital organ and assist in the treatment of male sexual dysfunction and erectile dysfunction.

[0049] Of course, in some other embodiments, if the requirement for the rapid air suction and air release functions of the vacuum chamber 3 in the second mode is not high, in order to save costs, the second valve 9 can also be cancelled, and only the second negative pressure pump 2 is used to have the function of circulating the air flow in the vacuum chamber 3.

[0050] In some embodiments, please refer to 1 to Figure 4, the vacuum negative pressure system further comprises a second three-way joint 10, the second three-way joint 10 is connected with the second exhaust end 22 of the second negative pressure pump 2, the first valve 8 and the second valve 9; the vacuum negative pressure system has a third mode, in the third mode, the main control panel 4 controls the first negative pressure pump 1 and the second negative pressure pump 2 to be closed, and the first valve 8 and the second valve 9 are opened, and the vacuum chamber 3 is communicated with the external environment.

[0051] Specifically, the second three-way joint 10 is provided to help reduce the length of the air pipe in the vacuum negative pressure system, to help simplify the overall structure of the entire vacuum negative pressure system, and to help achieve direct communication of the vacuum chamber 3 with the external environment through the first valve 8 and the second valve 9, and to help the vacuum chamber 3 exhaust in the third mode.

[0052] Please refer to Figure 4 In the third mode of the vacuum negative pressure system, the main control panel 4 controls the two negative pressure pumps to be closed, and the first valve 8 and the second valve 9 are opened, and the first valve 8 and the second valve 9 can be set as normally open valves, so that the third mode is a mode in which the entire vacuum negative pressure system is not working, that is, a mode at the end of treatment. In the first mode and the second mode of the vacuum negative pressure system in the working state, the vacuum chamber 3 is in a negative pressure state, and the target part of the human body is in a negative pressure state. After the treatment is completed, the target part of the human body needs to be taken out of the vacuum chamber 3. In order to facilitate the release of the restraint of the target part of the human body through the vacuum chamber 3, the vacuum negative pressure system is provided with the third mode, in which the vacuum chamber 3 is communicated with the external environment, and the external high-pressure gas can enter the vacuum chamber 3 through the second valve 9, the first valve 8 and the buffer gas tank 5 in sequence (the direction of the arrow with a dashed line in the figure is the direction of the gas flow), quickly releasing the restraint of the target part of the human body in the vacuum chamber 3 under the negative pressure, and also achieving the inflation of the buffer gas tank 5, facilitating the next use of the user.

[0053] Due to the different sensitivity of users to pain and the different bearing force of the target part of the user to the negative pressure, in some embodiments, the vacuum negative pressure system can further comprise a pressure relief valve (not shown in the figure), which is installed in the vacuum chamber 3, the main body of the pressure relief valve is arranged in the vacuum chamber 3, and the pressure relief valve has a switch exposed outside the vacuum chamber 3. The pressure relief valve is in a normally closed state. In the first mode and the second mode of the vacuum negative pressure system, if the user feels pain caused by the negative pressure of the vacuum chamber 3, the user can operate the pressure relief valve switch outside the vacuum chamber 3 to open the pressure relief valve, increase the air pressure in the vacuum chamber 3, and relieve the pain caused by the negative pressure.

[0054] Of course, in the structure of the vacuum negative pressure system provided with the pressure relief valve, the vacuum negative pressure system can not be provided with the third mode, and after the vacuum negative pressure system ends the working state, the user can operate the pressure relief valve to increase the air pressure in the vacuum chamber 3, so as to quickly release the restraint of the user by the vacuum chamber 3.

[0055] Or in other embodiments, the pressure reducing valve can also not be set, through the main control board 4 control the first negative pressure pump 1 and the second negative pressure pump 2 power, to avoid the negative pressure pump suction volume or suction pressure is too large and cause the vacuum chamber 3 in the air pressure is too low to make the user produce pain.

[0056] Some embodiments, the negative pressure pump can be for alternating electromagnetic pump, alternating electromagnetic pump applied to the vacuum negative pressure system, can produce greater air pressure wave in the vacuum chamber 3, which has a great relationship with the structure of alternating electromagnetic pump. Alternating electromagnetic pump for access to alternating current, such as can be directly connected to 24V or less low voltage AC, please refer to Figure 5 , alternating electromagnetic pump has a suction port 101, exhaust port 102 and connected in the pump gas channel 103 between the suction port 101 and the exhaust port 102, the suction port 101 forms the suction end of the negative pressure pump, the exhaust port 102 forms the exhaust end of the negative pressure pump; pump gas channel 103 is provided with a suction gas chamber 104 and exhaust gas chamber 105, the suction gas chamber 104 is close to the suction port 101, the exhaust gas chamber 105 is close to the exhaust port 102, the pump gas channel 103 between the suction gas chamber 104 and the suction port 101 is provided with a suction check valve, the pump gas channel 103 between the exhaust gas chamber 105 and the exhaust port 102 is provided with an exhaust check valve, the suction check valve and the exhaust check valve can only make the gas in the pump gas channel 103 flow from the suction port 101 to the exhaust port 102.

[0057] Alternating electromagnetic pump includes suction drum membrane, exhaust drum membrane 107 and swing piece 108, the suction drum membrane is located at the position of the suction gas chamber 104, the suction drum membrane is sealed with the pump gas channel 103, the exhaust drum membrane 107 is located at the position of the exhaust gas chamber 105, the exhaust drum membrane 107 is sealed with the pump gas channel 103; swing piece 108 is connected between the suction drum membrane and the exhaust drum membrane 107, swing piece 108 is the moving part in the negative pressure pump, the suction drum membrane and the exhaust drum membrane 107 are arranged in parallel, the swing piece 108 can swing towards the suction drum membrane to compress the air in the suction gas chamber 104, so that the gas in the suction gas chamber 104 flows towards the exhaust gas chamber 105; swing piece 108 can also swing towards the exhaust drum membrane 107 to increase the volume of the suction gas chamber 104, through the one-way valve from the air in the vacuum chamber 3, and compress the volume of the exhaust gas chamber 105, so that the gas in the exhaust gas chamber 105 is discharged from the exhaust port 102 along the exhaust check valve.

[0058] The alternating electromagnetic pump further comprises winding coil 109 connected with power supply wire 110 for inputting alternating current; swing member 108 has magnetism, and winding coil 109 can drive swing member 108 to swing between air suction drum membrane and air exhaust drum membrane 107 under the action of alternating current after being electrified. One cycle of alternating current is the same as one pumping cycle of the alternating electromagnetic pump, so that the pumping cycle has two different pumping periods: the first period is the period in which swing member 108 moves towards air exhaust drum membrane 107, during which air suction port 101 sucks air in vacuum chamber 3 and air exhaust port 102 exhausts gas in pumping channel 103; the second period is the period in which swing member 108 moves towards air suction drum membrane, during which the alternating electromagnetic pump neither sucks air nor exhausts gas under the action of one-way valve, so that the pumping flow in the first period is greater than that in the second period, and the pumping flow in the first period is the maximum. Since air suction chamber 104 and air exhaust chamber 105 are arranged in the alternating electromagnetic pump, the alternating electromagnetic pump helps to increase the pumping flow of the alternating electromagnetic pump, and two alternating electromagnetic pumps applied in the vacuum negative pressure system help to increase the air pressure wave in vacuum chamber 3; in addition, the pumping flow of the alternating electromagnetic pump can be increased by increasing the power input into the alternating electromagnetic pump, so as to further increase the air pressure wave in vacuum chamber 3.

[0059] Of course, in other embodiments, direct current can also be input into the negative pressure pump, and the power supply can be modified, such as arranging brushes on the positive and negative poles of the power supply. During rotation of the power supply, the positive brush alternately contacts the positive power supply wire 110 and the negative power supply wire 110 of the negative pressure pump, so as to actually input alternating current into the negative pressure pump.

[0060] Or in other embodiments, the negative pressure pump can also be a plunger pump or a diaphragm pump, etc. The pumping flow of the negative pressure pump can be increased by increasing the size of the air chamber in the plunger pump or diaphragm pump, so as to increase the air pressure wave in vacuum chamber 3.

[0061] In some embodiments, in order to facilitate the manufacture of the vacuum chamber 3, the vacuum chamber 3 can be provided in a split structure. The vacuum chamber 3 can include a first chamber body 31 and a second chamber body 32. The first chamber body 31 is a cylindrical structure having a first opening 321 and a second opening. The first opening 321 is used for sealing contact with the human body, and the target part of the human body enters the first chamber body 31 through the first opening 321. The second chamber body 32 is used to block the second opening of the first chamber body 31. The second chamber body 32 is provided with a plurality of interfaces. The second chamber body 32 is in communication with the negative pressure pump through the plurality of interfaces. The second chamber body 32 can be a semi-spherical shell. The pressure reducing valve is arranged on the second chamber body 32 and corresponds to the axis of the first chamber body 31, so as to facilitate the operation of the user. An indicator light (not shown) can also be arranged in the second chamber body 32. The indicator light can be electrically connected to the main control board 4. The connecting wire passes through the interface of the second chamber body 32 to control the indicator light to be bright or dark through the main control board 4. For example, the indicator light can be bright in the first mode and the second mode, and the indicator light can be dark in the third mode.

[0062] Of course, in other embodiments, the vacuum chamber 3 can also be integrally formed, which facilitates the assembly of the entire vacuum negative pressure system.

[0063] The above application of specific examples is used to illustrate the present application and is used to help understand the present application, and is not used to limit the present application. For those skilled in the art to which the present application belongs, according to the idea of the present application, a number of simple deductions, deformations or substitutions can be made.
